I have always been confused about the interaction between the speaker and amp and have sought clarity from other KZreadrs. With your explanation and visuals, I finally got it. Thank you Hans.

Finally ! A proper and understandable explanation for the layman.

After commenting I read some other comments, and well it is unanimous, Hans is good at explaining things in a way that most can understand and few will forget. I probably older than Hans but he commands my respect like a teacher or mentor. I love that.

Truly excellent! This topic has puzzled me for years. You have prepared me to understand this topic at a deeper level. Thank you!

Thanks for dimming it down for me. Also thanks for not over simplifying it either. More videos showing off your testing please

Thank you. Now I know I can connect my 6 Ohm speakers to my 4 ohm system.

Thank you Hans! I listened to parts of your explanation two or three times, then the sound test; first on my tv, then on my tv through my stereo, then via my my computer through the stereo and finely for the first time through the 4 ohm output. Like so many others below understanding loudspeaker impedance for my self; has given me the courage use my 4 ohm output. Someone who is a genuine expert is almost imposible to find, I have asked high end retailers that have sold me my equipment and their advice amounted to um not shore ,safer to stich to 8 ohms. In many of your of your videos much of the content goes above the head of a computer illiterate like me but there is always something that goes klick and you have resolved some question a have been trying to answer. You continue to be my first "port of call" for information.

I bought some pre-owned Magnepan 20.1s, which are specified as 4 ohm speakers. Since I use them in my home theater as well as for music, I hooked them up to my Yamaha RX-a1070 AVR, which is supposed to have dynamic power of 210 watts at 4 ohms. Since I listen to music at relatively loud levels, I guessed there might be a problem with overheating. Sure enough, the Yamaha got quite warm. So I bought a Emotiva A-300 which provides 300 watts at 4 ohms (obviously, I'm more interested in value than seeing how much I can spend). I still drive the center and surrounds on the Yamaha and only the Maggies on the Emotiva and problem solved. Neither the AVR or the Emotiva gets hot, even at high volume and the Maggies sound fantastic.

I'm a geek (Measured impedance curves and plotted the graph manually 40 years ago). I always find it interesting trying to explain to people that the reason a woofer or woofer/mid's impedance rises is in part because there a a big air core coil in series with it, just like a crossover. The voice coil, of course. Glad you mentioned that a steep phase angle occurring in the same vicinity as an impedance dip is tough to drive for lower end amps. Nice job. I'll refer this to friends/customers. I have trouble staying as concise as you.

Beautifully explained, Hans. I have an old 80's Krell Power Amp that needs some new Cap replacements due to old age. In its prime, it could drive very awkward loads with ease. 2 ohms would suck a huge amount of power from the amp & wall, and things would become very warm as a result. Any lower and you're approaching a short-circuit. I had a pair of AR 90's back then ... fantastic for the time. They had multiple 4 ohm drivers, though I understand there was a revision with the design. It was at this time I realised why power amps are so important.

wow! you saved me a load of time and tons of readings to try to understand this. I usually pay back great videos by SUBSCRIBING. Thank you!

Thank you Hans from Canada. A very good explanation of speaker performance. Also your other websites. My Sony amp - a mediocre one - has a 6 amp output. My two sets of speakers are also Sony and are 6 ohm speakers. I like to add the second set of speakers, and already have been told that I have to add a 3-4 ohm resister in series with the parallel wired speaker, for each one. This way the amp will perform well with about 6-7 ohm speaker impedance. I like your detailed explanation, en dank je wel hoor !.

Hans, great dissertation on Ohms. My question is two fold: I have paralleled two pairs of 8 Ohm rated speakers; 1 pair of Elacs and 1 pair of Fluance Bookshelf speakers. They are attached to a Denon DRA-800H Receiver. Posters all over the web have advised against this as the claim is Receiver and/or speaker destruction. The Denon also has a SW and another pair of Elacs connected to the A Speaker output. The Denon has shut down after playing CDs for awhile. I disconnected the A speakers , seemed better , but you can feel the Denon getting very warm. I now have a separate IOTA VXSA3 Preamp which is rated at 40Watts Per channel at 4 Ohms, 80 Watts at 8 ohms. I connected the paralleled speakers to this unit, and it plays slightly warm but not hot nor has it shut down. Will playing paralleled speakers in this fashion damage the Amp or Speakers . They playing very well together btw. No. 2 - Where do I connect the red and black leads from my multi-meter to the AMplifier (Receiver) to measure the ohms with the paralleled speakers ? It is an old Radio Shack meter which works when testing batteries, so I presume it still functions? Thx for your time and advice.

I was able to get some Martin Logan’s esl 9 speakers for superrrr cheap which said to operate at 4 ohms. but we only have a denon receiver that runs at 8ohms. We use it in a system where the two esl 9 speakers are front left and right and then bookshelf speakers for surround left and right and then also a center speaker.

Most Marantz products can deliver sufficient current to work with 4 Ω loudspeakers, but I can't guarantee it though.

The speaker is a complex load for any amplifier, the associated inductance and capacitance makes frecuency distorsion and if we also add the fact that it is an electromechanical component in itself the damping factor and the resonance of it complicate the thing a bit more. In short it looks like anything but a pure resistance at any frequency. All these factors have a negative influence in a performance it is usually does not exceed 25..30%...if you apply 1W electrical in the speaker you really listen sound equivalent to 0.25...0.30W in the best conditions. The rest power leakage for hot. Thank you for your clear explaination. I build tube amplifiers for hobby. Thanks a lot.

Great video! Loved your explanations except your quote from Einstein about energy. He might have said that, as most people who have studied and/or taught science have at some point have. However, it didn't originate with Einstein and was formalized as "The Law of Conservation of Energy" which preceded his birth by many years. Einstein did further this law by including mass as a form of energy, hence E=mc^2.

Thank you Hans. Great explanation. A few questions: 1. I don't see how the graph indicates your speaker is 8 Ohms. Can this be determined by this graph? 2. For a speaker that reads that it is 8 Ohms for example, I'd like to know what frequency manufacturers might use to measure the impedance. Many small analyzers use 1kHz and some sites state 250 - 400Hz but the impedance changes based on frequency. My concern is with measuring speakers that have no markings and measuring cabinets with multiple speakers. 3. What is the relationship, if any, of the impedance(say an 8 ohm speaker) to the resonant frequency of the speaker?

@TheHansBeekhuyzenChannel

4 жыл бұрын

As I said in the video, there are no 8Ω speakers. There are speakers that measure 8Ω at a given frequency, usually 1000 Hz. The most important frequency area for impedance is in the lows since there the most power is needed. What you want is the wanted impedance - 8Ω in your example - with a low phase.

Hi! I have a question. If the impedance relates to the "efficiency" and power handling at each frequency, does that mean we can view the impedance curve as sort of an equalizer profile? If a speaker has a huge ohm spike at say 50hz, does that mean it'll play louder/quieter at that frequency than a hypothetical speaker with a completely flat impedance curve? If that is true, does that also mean that connecting an amplifier with different ohms or connecting multiple speakers in series/parallel can chance the way a speaker sounds as if you boosted a couple of those frequencies where the impedance is higher? Sorry if I worded that poorly

@TheHansBeekhuyzenChannel

Just remember that the lowest value specified for the amp should not be lower than the lowest value specified for the speakers. So when connecting a 4 to 8 ohm speaker to a 6 to 16 ohm amplifier you risk destroying the power transistors in your amp.

As said, speakers never are 8 ohms. Try both options and use the one that sounds best.

Newbie question regarding impedance matching. I have a Yamaha RX V 3073 which I am currently using to run a pair of Dynaudio Emit M20s which have an impedance of 8 ohms. My Yamaha receiver has the option to use either an 8 ohm or 6 ohm impedance. Yamaha recommends I use the 6 ohm setting when using 4 ohms. Other audio advice I have received online suggests to leave the switch at 8 ohms in order to supply the speaker with the highest voltage and current. According to these sources the switch simply limits the power supplied to the speakers instead of matching impedance speakers. Will I damage either the receiver or speaker if I use the 8 ohm setting on speakers with a 4 ohm impedance? Which would be more likely to be damaged the speaker or the receiver? Logically it would appear that the receiver would be more likely to be more damaged due to overheating. I accidentally ran the 4 ohm speakers on the 8 ohm setting on the receiver for a few minutes and noticed some distortion at moderate volumes. Did I damage the tweeters? I haven’t noticed any further distortion after switching the receiver back to 6 ohms using the 4 ohm speakers. Is it easy to damage tweeters and how long would I have to run them distorted to truely damage them? Apologies for this convoluted post but am concerned about damaging my relatively new speakers. Any advice is appreciated. Thanks.

yes you can use them but as explained in the video you can only play them at mid range volume or less......playing at a high volume will most likely result in the amp heating up (your amp says 8-16 ohm but your speaker has a higher resistance of 6 ohm which will require more power from the amp). if you have a good amp it should have a safety switch off circuit when the power demand is too high otherwise it will overheat and it will fry it.

High current-delivery and high damping factor?

My take on damping factor is that it helps control the woofer excursions and that damping factors, above say 50, aren't necessary. A good DF range?? Maybe between 30 and 50. I think that WHERE your speaker impedance drops is more important than WHAT it drops to. Low impedances at 20kHz where there's little energy shouldn't adversely affect amp performance. At 1kHz you're fucked.

awotnot A normal amplifier is a stereo amplifier. it means it have two amplifiers inside, on for left speaker, and one for the right. There are a red and a black terminal for each amp. If you connect two 8ohm speakers to the same terminal, the impedance is 8/2 witch result in 4 ohm impedance for that output, this is called pararell wiring. But if you wire first to the terminals on one speaker, and from that one to the next, it is called series, and the total impedance will be 2*8 witch is 16ohms! so there is a massive difference

@@okspicks so you think i should run speaker wire to one speaker (from each channel ; left and right) and then run a secondary wire from that speaker to the second speaker of each channel i hope that makes sense i kind of 99% know that's what you meant - but just checking because i'm such a clutz and if so ... that should give me ohm impedance of 8 or 16 rather than under 8 or even far less - correct

Shiploads??? LOL!

One thing I still don't understand. When having a 4 ohm amplifier, with speaker terminals behind the amp made for four speakers, what is the deal with that? Using four speakers from what I understand is that you have to use 8 ohm speaker in first slot and 8 or more ohms in second slot. So how dangerous is to use 4 ohm speakers in first slot and 8 ohm speakers in second speaker slots at the same time?

If your amp is specified for 8Ωonly, you can not use 4Ω speakers.

This answers my question that i have been asking everyone,thanks Hans,i own a pair of Sony 4 ohm speakers and tried to hook them up to a 8 ohm Sansui amp,it sounded terrible,i got alot of clipping when i increased the volume,i ended up buying a pair of Yamaha 8 ohm Speakers.
